DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 492,623, dated February28,1893.

Application filed May 4,1892. Serial No. 431,844. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL F. DONEGAN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Side-Dump Wagon, of which thefollowing is a specification.

My invention relates to that class of dump wagons in which the bed ispivoted to tilt sidewise in order to enable the wagon to be driven alongside of an embankment and the load dumped over the edge thereof.

The object of my invention is to so arrange and proportion the variousparts that the greatest capacity can be secured with a minimum weight ofmaterial in the bed.

My invention comprises the combination in a dump wagon of the runninggears; a frame rigidly fixed to the bolsters of such runninggears andcomprising an upper and a lower girder beam; a swinging side wall hingedto the upper girder and provided with latches adapted to engage catchesarranged upon the lower girder when such side wall is closed; suchcatches; a tilting bed comprising afloor and a side wall securedtogether and mounted upon such running gears and pivoted to tilt towardsuch swinging side wall, and means for securing the tilting bed to thelower girder.

My invention also comprises the combination of the supporting beamprovided at each end with a transverse groove and a semi-cylindricaljournal bearing in such groove, and a journal bearing formed of strapmetal, secured upon the bolster and having a portion bent upward at twopoints above the plane of its body and having the portion between suchpoints arranged to form a journal bearing for the semi-cylindricalportion of said beam, whereby I am enabled to form a simple, light,artistic and strong journal at a minimum expense.

The accompanying drawings illustrate my invention.

Figure l is a plain side elevation of my improved side-dump wagon inposition to receive a load. Dotted lines indicate the position of partswhen the wagon is in the act of dumping. Fig. 2 is a plain frontelevation showing the bed tilted in the act of dum pin ga load; Thelower part of the running gears being broken away to contract the view.Fig. 3 is a plain front elevation with the bed untilted. Fig. 4 is afragmentary sectional view illustrating the means I employ for pivotingor journaling the bed to therunning'gear.

A indicates the ordinary running gear of a wagon.

B indicates the tilting bed including the bottom b and the side wall 1)rigidly fixed thereto. The bed is provided with two end walls b" rigidlysecured to the bottom and side wall. The bottom b is mounted upon asupporting beam 0 which extends longitudinal of the wagon and is pivotedor journaled upon the front and rear bolsters D D approximately mid-wayof their length.

The means I employ for pivoting the bed upon the bolsters comprise thecombination of the beam 0 provided with the transverse groove 0 and thejournal bearing 0' situated in such groove and the journal bearing strapE formed of strap metal and arranged to be secured upon the bolster andhaving a portion of its body bent upward at two points above the planeof its body and having the portion 6 of its body between suchpointsarranged to form a journal bearing for the semicylindrical portionwithin the groove 0 of the beam 0. By this arrangement the walls of thegroove 0 engage with the sides of the strap E and prevent the beam andwagon bedfrom slipping end-wise.

The swinging side wall or gate B is mounted upon an upright frame Gwhich is rigidly secured to the bolsters D D. Such side wall is hingedto the upper girder of the frame by hinges g and is arranged to swingoutward when its lower portion is not secured to the frame.

To provide simple and convenient means for detachably securing the loweredge of the hinged side wall B to the frame, there are pivoted to theswinging side wall suitable latches H H near the lower edge of suchwall. To the upper ends of such latches is pivoted a connecting rod hwhich is pivoted at one end to the bolt operating lever h which ispivoted to the bar G attached to the lower edge of the gate or swingingwall and is arranged Within reach of the driver at the front end of thedamper. The lowerends of the latches are arranged respectively to engagethe catches h (which are mounted on the girder beam g of the frame G)when it is desired to lock the gate or swinging wall 13 to the frame G.

The end walls b" are beveled from near the bottom of the bed next to theswinging side Wall 13', upward and backward to form the diagonalshoulder 11" which allows the bed to tilt toward the frame G sufficientto dump the load, and engages the frame G to prevent the bed fromtilting too far.

X indicates wings made of sheet steel or other suitable material securedto the frame G and arranged on the inside of the end walls I)" toprevent escape of the material over the beveled portion of such walls.

I is a chain to prevent the side wall I) of the bed from spreading out.

J J are braces arranged to hold the frame G in rigid connection with thebolsters D D.

K is a bed stop and support arranged upon the bolsters to receive andassist in sustaining the closed side of the bed when in position toreceive the load. The girder or beam g of the frame G is arranged in thepath of the floor b and also assists to prevent the bed from tilting inthe wrong direction. L is alink attached to such girder beam of theframe G and is arranged to receivea hook Z which is pivoted to thebottom I) of the bed, to detachably secure the bed to the frame toprevent the bed from dumping when it is desired to haul the load aconsiderable distance. To remove the link from the hook Z, the hook isturned up as indicated in dotted lines in Fig. 1, when the link will bereleased. By arranging the swinging side wall between the two rigidgirders I avoid all danger of the side wall being pressed out or brokenby the pressure of the material in the bed when the wagon is loaded, andI am enabled thereby to make the bed much longer with-out making theweight excessive.

In practice the bed is placed in the position shown in Figs. 1 and 3,and the side B is locked to the frame G by actuating the lever h tothrow the bolts or latches II into engagement with the catches h. Thebed is secured to the frame G, by the link L and hook l, the load isplaced in the bed and transported to the place where it is desired todump it. When the bed is filled with material,the

gate 13 being locked, the material of the load confined between the gateand the bed wall I) prevents the bed from tilting, and practically nostrain is brought to bear upon the When the load is to be moved onlyhook Z.

a short distance the link need not be secured by the hook. When it isdesired to dump the load, the link being released, the lever h isactuated as shown in dotted lines in Fig. 1, to release the latches Hfrom their engagement with the catches h"; the load pressing outwardswings the gate or swinging side-wall B outward. The operator vpullsupon the handle M and tilts the bed as shown in Fig. 2. If, as isusually the case, the dump is inclined in the direction the load is tobe dumped, the bed is tilted with great ease. The load discharges bothabove and below the beam g of the frame as indicated in Fig. 2. Thesupporting beam 0 extends rearward from the bed and is provided with aclip or lever socket Y into which a lever may be inserted by a helper toassist in dumping when the wagon stands without any lateral slant. Asillustrated in the drawings, the bed B is short enough to swing clearinside of the bolsters.

It would not be a departure from the spirit of my invention to fix thebeam 0 to the bolsters and pivot the tilting bed thereon but I atpresent consider the construction shown to be preferable and the changeabove suggested is considered so obvious as to require no illustration.The girder beam g is braced by a truss rod 25 to prevent it from beingbroken by the weight of the material. The girder beam g projectsrearward from the rear bolster and is connected with such bolster by asuitable brace U to prevent the bed from racking endwise.

Now having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A dump wagon comprising the combination of the running gears; a framerigidly fixed to the bolsters of such running gears and comprising anupper and a lower longitudinally arranged girder beam; a swinging sidewall hinged to the upper girder and provided with latches adapted toengage catches arranged upon the lower girder when such side wall isclosed; such catches; a tilting bed comprising a floor and a side wallsecured together and mounted upon such running gears and pivoted to tilttoward such swinging side wall, and means for securing the tilting bedto the lower girder.
